Description

Technical Field

[0001] The utility model relates to the technical field of analytical chemical equipment, in particular to a medicine anti-pollution sampling device. Background Art

[0002] Pharmaceutical sampling contamination refers to the process in which the samples are contaminated by external factors or mixed with impurities due to various factors during the collection of pharmaceutical samples, thereby affecting the accuracy and reliability of the sampling results.

[0003] For example, a Chinese utility model patent (CN220289109U) discloses an anti-fouling sampling device for analytical chemistry, which records: "By driving the assembly to repeatedly suck clean water from the cleaning component into the sampling component and then discharge it, the internal cleaning of the sampling component is achieved, solving the problem of being unable to clean the sampling tube and needle." It also records: "Since multiple drugs often need to be pipetted in analytical chemistry experiments, the device cannot clean the sampling tube and needle. Each time a different drug is taken, the sampling tube and needle must be cleaned. Failure to clean them can easily lead to cross-contamination between drugs. Each use of the device requires manpower to disassemble and clean, which is very inconvenient and leads to low efficiency." Technical problems.

[0004] In summary, it can be known that the prior art utilizes flushing of the outside of the sampling tube and the needle and sucking clean water into the sampling component and then discharging it for internal cleaning. However, this method has the following technical problems: in this cleaning method, after the clean water used for cleaning the outside of the sampling component is used to clean the outside, some chemicals will be attached to the clean water. When the water containing the chemicals is sucked into the sampling component for internal cleaning, the water already contains chemicals, which leads to poor cleaning effect on the inside of the sampling component. With repeated cleaning of the interior, the chemical content in the water further increases, which still leads to poor final cleaning effect. For this reason, the present application proposes a chemical anti-fouling sampling device to provide a new technical solution to solve the technical problems mentioned in the above patents.

[0030] As described in the background art, after the clean water used in this cleaning method is used to clean the outside of the sampling component, some chemicals will be attached to the clean water. When the water containing the chemicals is sucked into the sampling component to clean the inside, the water already contains chemicals, which leads to poor cleaning effect on the inside of the sampling component.

[0035] The pharmaceutical anti-fouling sampling device provided by the utility model brings the clamping rod 24 out of the cleaning hole 25 by pulling the sliding rod 20, and rotates the connecting rod 22 to be clamped in the inside of the clamping groove 18 by the rubber sleeve 23, and then places the splash plate 19 on the top of the cleaning tank 9 through the second hydraulic rod 28, and passes water through the water inlet pipe 8, so that water is sprayed in the internal cleaning nozzle 10, and the inside of the sampling tube 15 is rinsed through the cleaning hole 25, and the outside of the sampling tube 15 and the outside of the needle 17 are cleaned through the external cleaning nozzle 11, so as to avoid secondary cleaning with water containing pharmaceuticals after rinsing, resulting in poor cleaning effect, and finally affecting the accuracy and reliability of the sampling results.

[0036] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0037] Embodiment 1:

[0039] A cleaning tank 9 is fixedly connected to the top of the fixed plate 3, and an internal cleaning nozzle 10 is fixedly connected to the interior of the cleaning tank 9. The internal cleaning nozzle 10 can spray water into the interior of the sampling tube 15 for cleaning, thereby avoiding secondary cleaning with water containing chemicals after flushing, thereby improving the cleaning effect of the sampling tube 15. The internal cleaning nozzle 10 is fixedly connected to the inside of the water pipe 6.

[0040] The interior of the cleaning tank 9 is fixedly connected to an external cleaning nozzle 11, which cleans the outside of the sampling tube 15 and the outside of the needle 17, thereby improving the anti-fouling effect of the device. The external cleaning nozzle 11 is fixedly connected to the inside of the water pipe 6, and the interior of the cleaning tank 9 is fixedly connected to a water outlet pipe 16, which is fixedly connected to the inside of the supporting shell 2.

[0041] The anti-fouling sampling mechanism 5 also includes a connecting box 12 arranged at the bottom end of the rotating mechanism 4. The connecting box 12 provides protection and support for the first hydraulic rod 13, thereby improving the stability of the device. The first hydraulic rod 13 is fixedly connected to the upper surface of the inner wall of the connecting box 12, and the output end of the first hydraulic rod 13 passes through the bottom of the connecting box 12 and is fixedly connected to a piston 14.

[0042] A sampling tube 15 is fixedly connected to the bottom of the connection box 12 , the piston 14 is slidably connected to the inner wall of the sampling tube 15 , and a needle 17 is fixedly connected to the outer wall of the sampling tube 15 .

[0043] A card slot 18 is provided on the inner wall of the connecting box 12, and a rubber pad can be added in the card slot 18 to improve the stability of the card rod 24 when it is inserted. A splash plate 19 is fixedly connected to the outer wall of the sampling tube 15, and a limiting groove 21 is provided on the splash plate 19.

A rubber sleeve 23 is fixedly connected to the outside of the card rod 24. The rubber sleeve 23 will produce a certain deformation when the card rod 24 enters the card slot 18 and the cleaning hole 25. When the card rod 24 is stabilized in the card slot 18 or the cleaning hole 25, the deformed rubber sleeve 23 will release a certain elastic force, reducing the situation where the card rod 24 falls off due to external force, thereby improving the stability of the device.

The connecting rod 22 is rotated to be clamped in the inside of the clamping groove 18 by the rubber sleeve 23, and water is passed into the water inlet pipe 8. The water flows into the connecting pipe 7 through the water inlet pipe 8, and then flows into the water delivery pipe 6 respectively. A part of the water entering the water delivery pipe 6 is sprayed out by the internal cleaning nozzle 10, and the sprayed water enters the interior of the sampling tube 15 through the cleaning hole 25, and the interior of the sampling tube 15 and above the piston 14 are cleaned, and the cleaning is completed. Afterwards, the piston 14 is controlled to rise by the first hydraulic rod 13, and the water inside the sampling tube 15 and located on the upper part of the piston 14 is discharged through the cleaning hole 25. When the piston 14 rises to above the cleaning hole 25, the water in the internal cleaning nozzle 10 flushes the bottom of the piston 14 through the cleaning hole 25, and is finally discharged through the needle 17 and the cleaning hole 25, thereby cleaning the inside of the needle 17. Part of the water that enters the water pipe 6 cleans the outside of the sampling tube 15 and the outside of the needle 17 through the external cleaning nozzle 11. The cleaned water finally falls into the inside of the cleaning tank 9, and is finally discharged through the water outlet pipe 16.
